My electric tongue jack (hitch) on my RV won't work (raise

Customer Question

My electric tongue jack (hitch) on my RV won't work (raise or lower). It is hook up to 30 amp power at the house. Everything else in the RV works, including AC. I disconnected power from the house and plugged into the truck, with engine running.
